- public class IndexedTriangleFanArray
- extends IndexedGeometryStripArray
The IndexedTriangleFanArray object draws an array of vertices as a set of
connected triangle fans. An array of per-strip
vertex counts specifies where the separate strips (fans) appear
in the vertex array. For every strip in the set,
each vertex, beginning with the third vertex in the array,
defines a triangle to be drawn using the current vertex,
the previous vertex and the first vertex. This can be thought of
as a collection of convex polygons.
-
IndexedTriangleFanArray(int, int, int, int[])
- Constructs an empty IndexedTriangleFanArray object with the specified
number of vertices, vertex format, number of indices, and
array of vertex counts per strip.
IndexedTriangleFanArray
public IndexedTriangleFanArray(int vertexCount,
int vertexFormat,
int indexCount,
int stripIndexCounts[])
- Constructs an empty IndexedTriangleFanArray object with the specified
number of vertices, vertex format, number of indices, and
array of vertex counts per strip.
- Parameters:
- vertexCount - the number of vertex elements in this object
- vertexFormat - a mask indicating which components are
present in each vertex. This is specified as one or more
individual flags that are bitwise "OR"ed together to describe
the per-vertex data.
The flags include: COORDINATES, to signal the inclusion of
vertex positions---always present; NORMALS, to signal
the inclusion of per vertex normals; one of COLOR_3,
COLOR_4, to signal the inclusion of per vertex
colors (without or with color information); and one of
TEXTURE_COORDINATE_2 or TEXTURE_COORDINATE_3, to signal the
inclusion of per-vertex texture coordinates 2D or 3D.
- indexCount - the number of indices in this object
- stripIndexCounts - array that specifies
the count of the number of vertices for each separate strip.
The length of this array is the number of separate strips.
- Throws: IllegalArgumentException
- if vertexCount is non-positive
OR indexCount is less than PRIM_SIZE OR sum of all stripIndexCounts
is NOT equal to indexCount.
( PRIM_SIZE is 1 for points, 2 for lines, 3 for triangles etc)
